RF4CE is based on the IEEE 802.15.4 Standard. IEEE 802.15.4 is a member of the IEEE 802.x family which includes wide area wireless networking protocols such as Wi-Fi (802.11x) and WiMAX (802.16 and 802.20), wireless local area networking solutions like ZigBee, and wireless peripheral area networking products like BlueTooth and others.
Even though there are several proprietary low-power wireless LAN solutions for sense and control networks, the open standard ZigBee/IEEE 8201.15.4 appears to have the most momentum. There are many ZigBee/IEEE 802.15.4 standards. (See Fig. 1.) Focused on a wide variety of commercial, home automation, and industrial markets, ZigBee provides a strong and dynamic standards body with an active marketing wing. ZigBee is applicable for a numerous low-data-rate, medium-range WLAN applications. ZigBee PRO is similar, but adds increased interference robustness for radio unfriendly environments. ZigBee PRO also includes increased range and supports an increased number of nodes. There are also various ZigBee Specialized Profiles that consist as ZigBee solutions for specific functions. These smaller more task-oriented profiles require less MIPS and Flash memory, as well as lower power consumption. Specialized profiles for Smart Energy, Remote Controls, and Home Automation have already been developed and released.
Still in development is the new ZigBee Green Power profile targeted to developers of energy harvesting solutions. It provides a guideline for the seamless connectivity of ultra low-power energy supplies with ZigBee networks and sensors.
Announced in June 2009, ZigBee Green Power is expected to become a completed standard soon. According to the ZigBee organization, Green Power will enable new extensions for ZigBee and ZigBee PRO networks and will offer an established, competitive marketplace for deploying switches, sensors, and controllers using harvested energy in residential, commercial, and industrial environments. A standard for power development for energy harvesters will give manufacturers greater flexibility when designing innovative ZigBee products and solutions.
